Description

We present the break points that have been identified in the IGS repro 1 IWV series by applying nonparametric rank-sum tests on the daily and monthly IWV differences of the IGS repro 1 reference dataset and the ERA-interim reanalysis output at the station locations. We also applied the same tests on the IGS repro 1 ZTD and IWV time series and compare all the identified break points with each other. Which ones are robust? Which are related to known instrumental changes?
